- There are seven Seabee ratings: BU--Builders, CE--Construction Electrician, CM--Construction Mechanic, EA--Engineering Aid, EO--Equipment Operator, SW--Steelworker and UT--Utilitiesman. While each is a specialist in his own area, each Seabee is expected to know enough about each others' ratings to do basic work.
